Step-by-step explanation:
Answer:
f(3) = 42
Step-by-step explanation:
f(x) = 3x² + 5x
Then
f(3) = 3(3)² + 5(3)
= 3×9 + 5×3
= 27 + 15
= 42
Answer:
V = 6 or V = -6
Step-by-step explanation:
Solve for V over the real numbers:
V^2 = 12^2 - 6 2 9
12^2 + 2 (-6) 9 = 36:
V^2 = 36
Take the square root of both sides:
Answer: V = 6 or V = -6

Answer:
The position is N 65° E from light house b and S 20° E.
Step-by-step explanation:
To get the bearing we subtract the angles and how it formed.
For light house A
340 means it's remaining 20° and it's almost a complete revolution signifying that it's in the SE position.
For light house B
245 means it's remaining 25° on the inside but 65° reading from the north position. Signifying it's on the NE position.
